Array

If i have an array called

myLayerArray = new Array();

1) How can I clear all data in it?
2) How can I clear last item added?

List Component
If i select an item in a list how can i pull the data attached to that item with a button

Off the top of my head, to clear all the data you could just redeclare the array:

myLayerArray = new Array();

And to clear the last item added:

myLayerArray[myLayerArray.length - 1] = null;

[silentweed]

myLayerArray.length = 0; // to empty the array

myLayerArray.pop(); // to remove the last element
